PROBLEM TO BE SOLVED: To provide a reinforcing structure whose construction work is executable in a relatively short period, and which increases resistance to bending stresses working on beams, without deteriorating habitability of an existing building. SOLUTION: A plurality of beam reinforcing members 31 and 32 made of precast concrete are pressed against the outside of an existing beam 12 by a PC steel rod 23 via mortar 29. A PC strand 22 is passed through a predetermined number of adjacent beam reinforcing members and a tensile force is introduced therein to connect them integrally with one another. A column reinforcing member 41 made of precast concrete is disposed on the outside of an existing column 11 between a predetermined beam reinforcing member and a predetermined balcony slab 13. A PC strand 43 is passed through the beam reinforcing member, the balcony slab and the column reinforcing member via blocks of joint mortar 28a, 28b and 28c and a tensile force is introduced into the strand to connect them integrally with one another.
